Ethanol caused altered mobility of the lipophylic probe,
1,6-diphenyl-1,3,5-hexatriene in plasma membrane preparations of
Saccharomyces cerevisiae. Because lipids had been shown to protect
yeast against ethanol toxicity, sterols, fatty acids, proteins, and
combinations of these were tested, but protection from growth
inhibition was not seen. Ethanol-induced prolonged lag periods and...
In this dissertation we consider the problem of
automating the design of access structures for relational
database systems. The main considerations are effective
and rigorous utilization of the users' usage patterns,
global treatment of the whole design and utilizing most of
the commonly known access structures.
We represent the usage...
The shallow water benthic habitat of the SW Beaufort Sea is frequently
gouged by the keels of ice pressure ridges. This natural physical
disturbance was hypothesized to be an important factor affecting the
structure of the benthic community. Smith-McIntyre grab samples were
taken from three discrete gouge axes and from...
